With high flow rates and low battery drain DC submersible pumps transfer water quietly and efficiently against low heads. Flow rate falls rapidly as the discharge head rises. Use the recommended hose size: undersized hose won't harm the pump but you will get significantly less flow. A good choice for light, intermittent duties handling cleanish bilge water. Large submersibles can shift water at an impressive rate without making a heavy demand on the battery. Not for continuous bilge pumping, for water with a lot of suspended solid matter, or for permanently submerged duties.

No Jabsco pump should be used for petrol, solvents or any liquid with a flash point below 37oC( 98oF)
